while the system is performing
the limit switch initialization routine. The system
will complete the initialization function by finding
the azimuth and elevation switch limits and then
go to the home position.
Steps 10 through 12 will speed the antenna’s acquisition of the
satellite when GPS input to the antenna is not present. It is not
required to complete the Antenna Gyro replacement process but
doing so will speed acquisition and improve system
performance. If you are not entering the latitude and longitude as
described in Steps 10 through 12, continue to Step 13 to complete
the process.
10. Determine the latitude and longitude of the vessel
location to the nearest degree.

Elevation Motor and Belt
Replacement
The elevation motor is mounted to the inside of the elevation
drive assembly support frame. Machine screw/washer and stop
nut sets hold the motor in proper position to maintain proper
tension on the toothed drive belt. When adjusting belt tension or
changing the belt, do not remove the screws from the motor side,
only loosen the external nuts on the belt side. Figure 4-7 shows
the arrangement of the motor, drive belt, and antenna pulley.
